Workaround for the performance issue with posting in large communities

Ruud@lemmy.worldmod to Lemmy.World Announcements@lemmy.world – 99 points –

We're still working to find a solution for the posting slowness in large communities.

We have seen that a post does get submitted right away, but yet the page keeps 'spinning'

So right after you clicked 'Post' or 'Reply' you can refresh the page and the post should be there.

(But maybe to be sure you could copy the contents of your post first, so you can paste again if anything would go wrong..)

Is the slowdown that it the instance has to send out updates about the comment to every other instance before returning a successful response? If so, is anyone working on moving this to an async queue?

Sending out updates seems like something that’s fine being eventually consistent

Ooh that’s a good remark ! I’ll see if that’s the cause

Reading more about how this works, sending out updates to each instance shouldn’t block the request from returning unless you have a config flag set to debug source.

It might be due to poorly optimized database queries. Check out this issue for more info. Sounds like there are problems with updating the rank of posts and probably comments too

So it looks like YOU SOLVED THE ISSUE with this reply! This led me to check the debug mode, and it was on! It turned that on when I just sterted the server and federation had issues....

We no longer seem to have the slowness!!
